From Start to Finish
Our Guiding Principles
These core values drive everything we do and ensure exceptional results for our clients.
Commitment
We are in this for the long term, not just the submission date. The people you meet at the outset are the people who prepare your claim, so you will not have to explain your business again each year. That continuity matters because the decisions that shape what you can claim are usually made long before the return is filed.
Transparency
You will always know what we are doing, why we are doing it and what it costs. We explain how we arrived at your claim value, where careful judgement has been required and why we have taken the approach we have. No surprises at the end, in either direction.
Accountability
We put our name to our work and take responsibility for the advice we give. Every claim is prepared to a standard we can stand behind. We can explain every recommendation, show how we reached it and, if anything needs revisiting, we deal with it.
Candour
If we do not believe we can help, we will tell you plainly and early, before you spend money finding out. If the likely outcome is less than you hoped, we will tell you that too. We would rather lose a fee than recommend something we do not believe is right for you.

Tell us about your business
Enter your best estimate of spend on qualifying R&D activity. This is not your total development, engineering or project budget.
Qualifying spend covers only the staff time, contracted-out R&D, externally provided workers, consumables, software, data licence and cloud costs attributable to work that sought a scientific or technological advance. Most companies overestimate this figure before a technical review, so treat whatever this produces as an upper bound rather than a target.
For periods beginning on or after 1 April 2024, overseas contracted-out R&D and externally provided worker costs are generally restricted. Limited exceptions apply where necessary conditions cannot reasonably be replicated in the UK; lower costs or overseas worker availability alone are not enough.
